Direct observation of cycloidal spin modulation and field-induced transition in Néel-type skyrmion-hosting VOSeO
T. Kurumaji, T. Nakajima, A. Feoktystov +6
We investigate the spin rotational structure of magnetic skyrmions in a tetragonal polar magnet VOSe2O5 via polarized small-angle neutron scattering (SANS). Spin polarization analy…
Topological Nernst effect of the two-dimensional skyrmion lattice
Max Hirschberger, Leonie Spitz, Takuya Nomoto +12
The topological Hall effect (THE) and its thermoelectric counterpart, the topological Nernst effect (TNE), are hallmarks of the skyrmion lattice phase (SkL). We observed the giant…
Ordering phenomena of spin trimers accompanied by large geometrical Hall effect
Shang Gao, Max Hirschberger, Oksana Zaharko +10
The wavefuntion of conduction electrons moving in the background of a non-coplanar spin structure can gain a quantal phase - Berry phase - as if the electrons were moving in a stro…
